Overview

This project aims to collect GPS location information and survey responses from backcountry
riders/sledders to better understand what types of terrain decision we make. Our focus
is on backcountry riders of all abilities and experience. You need not be an expert
backcountry rider to participate in this research.

Participation

If you are interested in taking part in this project and sharing your GPS ride information
and responding to a few simple questions, then follow the easy steps below (or download this PDF).

Please note that steps 1 and 2 only need to be done once. Steps 3 to 5 can be done
for every trip thereafter:

This application is free to use and you can choose to share your tracks, or keep them
private. You can also easily email them to us!

Once you have downloaded and installed this application on your GPS enabled smart
phone or tablet, then go into the settings and setup your email address preferences.
If you need help see the user guide online

You can also use a handheld GPS device / GPS watch etc., if you don't want to use
a smartphone.

NOTE: Step 1 and 2 only need to be completed once. Steps 3-5 need to be followed for
every trip that you want to submit to us.

*3.Track your trips.

Every time you go out for a ride, simply start this application and click “Track Ride”
and log your track.

While you are out, take photos of any key decision points – e.g. Did you see an avalanche
and then decide to ride elsewhere (take a photo of the avalanche). Did you dig a snowpit
and find out more information about the nature of the instability (take a photo of
the snowpit). Or did you stop and discuss the route ahead (take a photo of the route
ahead).

Once you have finished your trip, end by saving it. When you are back in cell phone
or internet coverage, please send us your track and any photos (go into “Rides”, click
on your tracked rides and share via email (click the track to go to ride details,
then click up arrow in the bottom right to email it to us). Please email your file to sleds@montana.edu.

*4. Automatic replyOnce we receive your track, we will send you an automatic email reply with a link to the post trip survey.

*5.Complete a short, post-trip survey.

Click on the link for the post trip survey from your smartphone, tablet or computer and complete the
survey. We need you to complete this survey after every trip, so that we have both
the track and the survey data. Together, these data will provide insights into decision
making. Here is that link: https://www.surveymonkey.com/

Or bookmark the website so you can easily navigate to the survey following every trip.

Confidentiality

We will not share your email address with anyone outside of the immediate research
group. We will only use your email address to link you track information with your
survey responses. We will also use your email address to contact you, should you win
one of our spot prizes. Good luck!

Frequently Asked Questions (FAQs)

Do I need to use RiderX?

No. We will certainly accept GPX files from GPS units and / or other smart phone
apps. Please email these to the email address sleds@montana.edu as you will then receive an automatic reply with a link to the post trip survey.
We have suggested that people use the RiderX application only because it makes it
easy for people to share their files with us - a standalone GPS or another app works
just as well for data collection, it's just that you need to connect / download and
then email the track (which is more work than sharing their track via the RiderX app). As a side note - no one working on this project is affiliated with the developers
of RiderX. This application is just one on the market that does most of what we need
it to for our project.

What about battery life?

If using RiderX then to reduce power usage, you will be tracked using triangulation
from cell towers (if within range), and by GPS if out of range. Regardless of the
method of tracking, RiderX will check battery life and stop tracking once the level
gets below a predefined threshold (20% by default). This ensures that you will always
have sufficient battery power to make emergency calls. You can adjust this threshold
to a lower value if you wish (e.g. 10%). Based on testing using a range of phones,
we have managed to track continuously for between 8 and 12 hours. Older phones, with
older batteries may manage less. You also need to keep your phone warm.

What about interference?

There has only been only a limited amount of work on this issue, however it does
seem that electronic devices (e.g. cell phones, radios, headlamps, MP3 players, GPSs,
etc.) can affect avalanche transceivers. The electronic devices affect the searching
beacon more than the transmitting beacon. Most manufactures of electronic equipment
do not mention possible interference between their electronics and avalanche transceivers.
However, a few diligent manufactures, such as Petzl, mention avalanche transceivers
specifically. This note that comes with the Petzl Tikka XP2 headlamp: "Warning, when
your lamp is lit and in close proximity to an avalanche beacon in receive (find) mode,
it can interfere with the operation of the beacon. In case of interference (indicated
by static noise from the beacon), move the beacon away from the lamp until the noise
stops, or switch off the lamp." In search mode, irregular readings and decreased range
can also be caused by other sources of electrical interference, such as power lines,
lightning, and electrical generating equipment. Based on one, very limited study (Barkhausen
2012), the distance between the electronic device and the avalanche transceiver seems
to be the key issue. Various avalanche transceiver manufacturers suggest 30cm (12
inches) to 50cm (20 inches) and based on the results from Barkhausen (2012) you should
attempt to keep them at least 40cm away from one another to minimize the impact of
the potential interference of your phone or GPS on your avalanche transceiver. Further
work is needed to examine issues around orientation / transceiver to device combinations
/ smart phone sending or receiving data etc etc. However in the meantime, we suggest
that the top pocket of your pack, or a thigh pocket on your pants might be a good
location for your phone or GPS.
